LOUIS, MISSOURI, ACORPORATION OF NEW JERSEY INSULATED RANGE Application filed September19, 1929. Serial No. 393,757.

This invention relates to improvements in insulated ranges the inventionbeing more specifically directed to theconstruction of the broiling andcooking ovens of arange and the lining therefor.

The primary object of the'invention is the provision of an improvedconstruction of broiling and cooking ovens for ranges.

A further object of the invention is the provision of an improved boxlining for the broiling and cooking ovensof a range.

Another and'further object of the invention is the provision of animproved box lining for the broiling and cooking ovens of a range, saidlininghaving an improved fiue arrangement and being constructed to slideas a whole. into a standard sized broiling and cookin oven of a standardrange.

A st1ll furth er object of the invention is the provision of a boxlining for the cooking and broiling oven of a range and a new manner ofassembly of the oven back wall to the body portion of the ovencompartment.

A still further object of the invention is .25 the provision of aconstruction to accomplish the purposes above described which is simpleand cheap of construction, highly eflicient in operation, and one whichmaterially cheapens the cost of assembly of a range by materiallyreducing the amount of time required in the assembly of the broiling andcooking ovens and the lining therefor.

Other specific objects, novel features of construction and improvedresults and imovens and lining therefor will appear from the followingdescription and accompanylng drawings; M

In the drawings:

Figure 1 is a view in strung out perspective of a broiling and cookingoven of a range with the oven back removed, the box lining for the ovensand the oven back wall.

Figure 2 is a perspective view of the box liningfor the ovens, a portionof the view being broken away and shown in vertlcal section.

Figure 3 is an enlarged fragmentary vertical sectional view through thetop rear corner of the assembled oven construction with proved operationof the broiling and cookingthe improved box lining and flue way inposition; j

Figure 1 is an enlarged fragmentary vertical sectional view through thefront end of the box lining illustrating the construction of that partof the lining.

Reference now being had to the drawings it will be seen that the ovenproper comprises a bottoni 5, side walls 6 and 7, and a top 8, all ofwhich are supported upon and in a front frame carries an oven door 11and a broiler door 12 which close the front of the oven structure whilethe rear of the oven structure is closed by the oven rear wall 13.

The range is of the insulated type and is 80 bottom frame 9 and a frontframe 10. The

provided at the inner sides of its walls and top witha suitableinsulating material 1 1 and in the assembly of the-ovens this is putinto 'place before the box lining is slid into the oven housing.

The box lining for the oven is'composed of two side walls 15 and 16, arear wall 17 and a top composed of two members 18 and 19 arrangedthroughout the majority of their areas in separated parallel relationforming between them a space 20. This box lining is preferablymade ofcopper bearing material, although other materials could be readilysubstituted, and in the assembly the side walls are provided withflanges 21 and 22 overlapping the rear wall of the lining and weldedthereto, although the parts could be bolted or riveted. Thepiece 18constituting the top of the lining at its longitudinal edges is bentdownwardly'as at 23 to meet the lining top piece 19 and has a portion 24which I parallels and abuts the top piece 19 for a being positioned asthus described are welded or otherwise suitably fastened together,

The rear wall 17 of the lining is provided with a flue outlet 27 whichcommunicates with the vertical flueway 28 which is welded or otherwisesuitably attached to the rear face of this lining member.

- The lining top at its rear edge is bent downwardly to form a flange 29which is welded or otherwise suitably attached to the upper edgeof therear wall of the lining but this flange is cut away intermediate itslength to form an opening 30 having communication with the space 20between the lining top members 18 and 19.

In the assembly of the cooking and broiler ovens the back wall 13 of theoven compartment is left OE and the box lining is shoved or slid as anentirety into the oven housing with the open front end of the liningtowards the oven and broiler doors and the open bot tom of the liningbeing closed by the bottom 5 of the oven housing.

As the oven compartment comprises both the broiler and cooking oven itwill be readily understood that a plate, although not shown,

is provided intermediate the height of the box lining to divide thelining and the oven into .the two compartments forming I the broilingand cooking ovens. This division plate which forms the top of thebroiling oven and the bottom of the cooking oven is positioned in ahorizontal line in a plane intermedate the top of the broiling oven door12 and the bottom of the cooking oven door 11, while the flue opening27is positioned centrally of the lining rear wall 17 from side .to' sideand just above where this division plate forming the bottom of thecooking oven will come. I

Of course it is essential for every oven to have a burner and a gassupply therefor, and as a consequence the oven housing wall 7 isprovided with an opening 30 while the box lining wall 16 is providedwith an aligned opening 31 for the passage of the burner mixing tube orthe fuel supply'pipe.

Most ranges today also have an oven thermostatic control and toaccommodate this apparatus the box lining wall 16 is provided with anopening 32 to accommodate the control mechanism of the thermostat and anopening 33 which is partially in the lining side wall and partially inthe lining top to accommodate the thermostatic member per se. Theopposite oven side wall 15 is provided with an opening 34 to accommodatea bracket for supporting the outer end of the thermostatic member. Asthe lining top member 19 would interfere with the passage of thethermostatic member into the lining this member is provided with atransverse U-shaped bend 35 opposite the openings 32 and 34 to provide aspace for the accommodation of this thermostatic member per se.

Due to this U-shaped bend 35 the space 20 terminates at its front end inthe transversely extending wall 36 forming a portion of this U-shapedbend.

As has been previously explained, this box lining is slid as an entiretyinto the oven housing it being understood of course that the insulatingmaterial 14 has been previously positioned and suitably held in the ovenhousing so as to permit the ready andeasy insertion of the box lining.

The housing comprising the cooking and broiling ovens is standard andidentical with housings heretofore known and used with the exceptionthat at its rear it is provided with longitudinally outwardly extendingangle irons or flanges 37 and 38 and horizontally outwardly extendingangle irons or flanges 39 and 40 positioned at the top and bottom of theoven housingrespecti'vely.

The rear wall 13 of the oven housing is also slightly different fromwhat has been heretofore known as standard in that it has an encirclingflange or angle iron 41 which telescopes the flanges 37 38, 39 and 40 ofthe oven housing and is sultably removably attttched to these angleirons by bolts 42 or the When the oven housing rear wall 13 is in placeit will be seen by reference to Figure 4 of the drawings that theflue-way 28 abuts the rear wall 13 of the oven housing and centrallydisposed at the upper edge of the oven rear wall 13 there is provided aflue box 43 and having an opening 44 which is in communication with theupper end of the box lining flue-way 28 and the opening 30 of the space20 at the top of the box lining.

This flue box is provided with a conventional collar 45 for thereception .and support of a take-oil pipe or conduit when desired.

Having described the invention it will be seen that the only outlet forthe products of combustion to escape from the I ovens is through thelining opening 27 and up the flue-way 28 to the flue box 43.

The separated horizontal top members 18 and 19 form at the top of thelining an air insulation and heat from this space 20 can escape throughthe opening 30 outwardly through the flue box 43 so that at the top ofthe range construction there is an air insula- Thus it will be seen thatI have provided an oven construction for ranges .which is quick andsimple of assembly and one which in respect to the oven housing requiresno alteration other than the provision of the. angle iron flanges and aslight alteration-of lining will be provided with means for the ovenrear wall so that the invention is readily adaptable to a standard ovenand will not affect the dimensions of either the height, width or depthof the oven chambers.

Although it is not illustrated in the drawings for the reason that anyof the well known constructions could be used, it will be understoodthat the interior side walls of 1thie s 1 ably supporting the oven racksand such broiler pans as go into the usual make-up of this part of acooking range.
